JohnWu commented on SOLR-1395:
------------------------------
oh, TomLiu:
I use the MultiEmbeddedSearchHandler in query core, but the request also can
not through the code:
// add end
NamedList nl = resp.getValues();
nl.add("QueriedShards", shards);
// Added by tom liu
SolrDocumentList sdl = (SolrDocumentList)nl.get("response");
if( sdl == null ){
nl.add("response", new SolrDocumentList());
if( log.isWarnEnabled() )
log.warn("SolrServer.SolrResponse: no
response");
}
if you use the katta start the embedded solr, the queryComponent is the
necessary component for solr, so the above code will throw the exception of
cast DocSlice to SolrDocumentList.
Does I miss some step?
what means but XMLWrite or EmbeddedServer returns SolrDocumentList from
DocList.?
